The moved sand caused by the wave is one of the important issue in coastal engineering. Moved sand of the coastal refers that wave and current ,cause sand suspended and moved, and it also caused the change of seabed along the coast. To estimate the change of sediment and establish the mechanism of sediment is very important in coastal engineering design.
The series of hydraulic model experiments in wave flume are used to observation the relationships between moved sand and incident water wave condition.
In this thesis, the movable-bed model of slope 1/45¡B1/30 ,which moved sand were estimated with surveyed from images of flume glass, and use image processing technique, we can calculate actual situation of movable-bed change. We also use the braces of sensor which was new design, set braces near surf zone, obtain the change of the pore pressure under the movable-bed and analysis the relationships between moved sand and incident water wave condition.
